1985
key -> value
key -> value movie -> stallone cobra release_date -> 1985
SET release_date “1985” GET release_date
tables
id movie release_date genero 1 Stallone cobra 1985 1 2
matrix 2000 1 id genero 1 ação
insert into actor (name) values (“sylvester stallone”); select name from
actor;
Graphs
Stallone Cobra Sylvester Stallone Os mercenários
nquad
_:actor <name> “Sylvester Stallone” _:movie <name> “Stallone Cobra” _:movie <release_data>
1985 _:movie <actor> _:actor
queries
gremlin
g.V[[title:'Stallone Cobra']].[[type: ‘Actor’]]
cypher
MATCH (ee:movie)-[:ACTOR]-(actor) WHERE ee.movie = "Stallone Cobra" RETURN ee, actor;
Graphql +-
{ search(func: eq(name: “Stallone Cobra”) { name actor { Name
} } }
Search, column based, genoma, time series, etc.
